2003-08-11Print % signs before register names; turn off "noprefix" mode in gas output.Brian Gaeke
Fixes test case test/Programs/LLVMSource/2003-08-03-ReservedWordGlobal.ll. Also: Refactor implicit-uses printing into its own method. Remove a couple of unused variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7737 91177308-0d34-0410-b5e6-96231b3b80d8

2003-08-03Remove illegal, unsupported escapes. This fixes program: Ptrdist-bcChris Lattner

2003-08-03* Sort #includes, remove dupliatesChris Lattner
* Use .zero to emit padding between struct elements * Emit .comm symbols when we can, this dramatically reduces the amount of gunk we have to print * Print global variable identifiers next to initializer more nicely. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7551 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-31I think local symbols in X86 GAS have to start with .L, not justBrian Gaeke
.; so I have changed the basic block markers to start with .L. I also broke up a >80char line. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7452 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-24Use unified CWriter-X86/Printer name mangler. Do not bother usingBrian Gaeke
SlotCalculator in CWriter. (Unfortunately, all this means a lot of X86/Printer's methods have to be de-constified again. Oh well.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7299 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-24It doesn't appear that we need to #include these.Brian Gaeke
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7291 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-24Constify most methods. We could have constified doInitialization andBrian Gaeke
doFinalization too except that would have made them shadow, not override, the parent class :-P. Allow *any* constant cast expression between pointers and longs, or vice-versa, or any widening (not just same-size) conversion that isLosslesslyConvertibleTo approves. This fixes oopack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7288 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-23Printer.cpp: Ditch addRequired/getAnalysis, because they leaveBrian Gaeke
Printer::doFinalization() out in the cold. Now we pass in a TargetMachine to Printer's constructor and get the TargetData from the TargetMachine. Don't pass TargetMachine or MRegisterInfo objects around in the Printer. Constify TargetData references. X86.h: Update comment and prototype of createX86CodePrinterPass(). X86TargetMachine.cpp: Update callers of createX86CodePrinterPass(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7275 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-23Add, rewrite, and/or reformat many comments.Brian Gaeke
Stop passing ostreams around: we already have one perfectly good ostream and we can all share it. Stop stashing a pointer to TargetData in the Pass object, because that will lead to a crash if there are no functions in the module (ouch!) Instead, use addRequired() and getAnalysis(), like we always should have done. Move the check for ConstantExpr up before the check for isPrimitiveType, because we need to be able to catch e.g. ubyte (cast bool false to ubyte), whose type is primitive but which is nevertheless a ConstantExpr, by calling our specialized handler instead of the AsmWriter. This would result in assembler errors when we would try to output something like ".byte (cast bool false to ubyte)". GC some unused variable declarations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7265 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-23Simplify code by using ConstantInt::getRawValue instead of checking to seeChris Lattner
whether the constant is signed or unsigned, then casting git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7252 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-11If we have a constant pointer reference to a function, we were printingBrian Gaeke
out the entire llvm disassembly for the function at global constant-output time, which caused the assembler to barf in 164.gzip. This fixes that particular problem (though 164.gzip has other problems with X86 llc.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7168 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-11Fix some serious floating-point bugs (fixes test cases such as Oscar,Brian Gaeke
Fhourstones, McCat-vor, and many others...) Printer.cpp: Print implicit uses for AddRegFrm instructions. Break gas bug workarounds up into separate stanzas of code for each bug. Add new workarounds for fild and fistp. X86InstrInfo.def: Add O_ST0 implicit uses for more FP instrs where they obviously apply. Also add PrintImplUses flags for FP instrs where they are necessary for gas to understand the output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7165 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-07Insert workaround for GAS bug in assembling FLD/FSTP XWORD PTR [...]Brian Gaeke
instructions, by outputting them as bytes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7115 91177308-0d34-0410-b5e6-96231b3b80d8
2003-06-27Nice tasty llc fixes. These should fix LLC for x86 for everything inBrian Gaeke
SingleSource except oopack and Oscar. (Sorry, Oscar.) include/llvm/Target/TargetInstrInfo.h: Remove virtual print method. Add accessors for ImplicitUses/Defs. lib/Target/TargetInstrInfo.cpp: Remove virtual print method. If you really wanted this, just use MI->print(O, TM); instead... lib/Target/X86: FloatingPoint.cpp: ...like this. X86InstrInfo.h: Remove virtual print method. Define the PrintImplUses target-specific flag bit. X86InstrInfo.def: Add the PrintImplUses flag to all the instructions which implicitly use CL, because the assembler needs to see the CL in order to generate the right instruction. Printer.cpp: Ditch fnIndex at Chris's request. Now we use CurrentFnName to name constants in the constant pool for each function instead. This avoids keeping state between runOnMachineFunction() invocations, which is a no-no. Having MangledGlobals be global is a bogon I'd like to get rid of too, but making it a static member of Printer causes link errors (why???). Make NumberForBB into a member of Printer instead of a global, too. Make printOp and printMemReference into methods of Printer. X86InstrInfo::print is now Printer::printMachineInstruction, because TargetInstrInfo::print is history. (Because of this, we have to qualify the names of some TargetInstrInfo methods we call.) Print out the ImplicitUses field of any instruction we print that has the PrintImplUses bit set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6924 91177308-0d34-0410-b5e6-96231b3b80d8
2003-06-26Number constants from constant pool as CPIf_i where f is the function indexBrian Gaeke
and i is the constant pool index. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6920 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-25First draft of X86 LLC backend. This should be OK for small programs likeBrian Gaeke
Shootout, but it has some issues with bigger programs. Work in progress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6907 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6792 91177308-0d34-0410-b5e6-96231b3b80d8
2003-06-19Add Initialization and Finalization methods for the Printer pass,Brian Gaeke
to print various things on a module-by-module basis (currently, only the former is used). Don't print < > around names. The assembler can't take it. Print pseudoinstructions only as comments. The poor little assembler can't take that, either. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6789 91177308-0d34-0410-b5e6-96231b3b80d8

2002-12-05Target/X86/Printer.cpp: Add sizePtr function, and use it instead ofBrian Gaeke
" <SIZE> PTR " string when emitting assembly. Target/X86/X86InstrInfo.def: Tidy up a bit: Squashed everything down to 118 chars wide, wrapping lines so that comment is at the same point on each line. Rename "NoImpRegs" as "NoIR". (most instructions have NoImpRegs twice on a line, so this saves 10 columns). Also, annotate various instructions with flags for size of memory operand. (MemArg16, MemArg32, MemArg64, etc.) Target/X86/X86InstrInfo.h: Define flags for size of memory operand. (MemArg16, MemArg32, MemArg64, etc.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4932 91177308-0d34-0410-b5e6-96231b3b80d8
